Nadler's Formula

The Article is of poor Quality, it should include Nadler's Formular for the estimation of human blood volume. — Preceding unsigned comment added by 139.18.118.14 (talk) 15:45, 6 April 2013 (UTC)[reply]

Why does it seem like mammals bleed so much more than anything else?

I have looked offsite and confirmed that birds, frogs, fish, and mammals all have roughly the same ratio of blood to body weight. But we mammals seem a lot more prone to spilling our blood than anything else in the world, and I wonder why that is. This applies even in water ... e.g. a fish that gets bitten will not stain the water red and may go on swimming with surprisingly severe injuries, but when we slaughter whales, the water stains deep red for what seems like miles. Have mammals lost some evolutionary adaptation that protects other animals from severe blood loss? My first thought was that water pressure keeps the fish's blood from spilling out, but why are marine mammals (including human divers) not also protected by this phenomenon? Furthermore it seems that even terrestrial animals, outside of mammals, seem less prone to bleeding than we are. And I was surprised to find out that their blood volume is similar .... e.g. this frog picture led me to believe that frogs, being cold-blooded, have very small blood volumes and are able to survive even so because of differences in metabolism, but ... apparently the average tree frog has a blood volume of 75ml/kg, spot-on the exact same as humans.
